The Wera Tools 05073541001 is an 817 R SB Bitholding Screwdriver that measures 1/4" x 133 mm in size. It features a retractable bayonet blade that can be easily inserted in the power screwdriver or used in the chuck of an electric drill. This screwdriver is designed with Rapidaptor technology that allows for quick and easy bit changes, making it highly efficient for various screwdriving applications.

The Wera Tools 05073541001 is equipped with a multi-component Kraftform handle that ensures ergonomic screwdriving, minimizing fatigue and increasing comfort during extended periods of use. The handle provides an excellent grip and allows for precise handling, ensuring a safe and efficient screwdriving experience.

This screwdriver is compatible with bits that have a 1/4" hex head drive, as per DIN ISO 1173-C 6.3 and E 6.3, making it highly versatile and suitable for use in a variety of applications. Whether you are a professional mechanic, carpenter, or DIY enthusiast, the Wera Tools 05073541001 is an excellent tool that guarantees reliable and efficient performance.

When the unique telescopic blade is lowered into the handle, fast, easy screw-driving action is possible, even in the tightest spots!

By pushing the clamping sleeve, the telescopic blade can be extended out of the handle and the compact tool becomes a full-sized screwdriver.

If the clamping sleeve is pushed again the telescopic blade can be taken out of the handle, and be used as a machine bit adaptor.

The bit can be pushed into the adaptor without moving the sleeve. The lock is activated automatically as soon as the bit is applied to the screw. Bits are held securely and wobble-free.

Simply push the sleeve forward to change the bit. The spring mechanism lifts the bit off the magnet and unlocks the tool. The bit can be easily removed. The rapid-out function makes it easy to remove even the smallest bits without extra tools.

The Rapidaptor quick-release chucks hold ¼" DIN ISO 1173-C 6,3 and E 6,3 as well as Wera series 1 and 4 bits.

The free-turning sleeve allows screw steadying at the start of the screwdriving process. This makes it easier to apply the tool to the screw and prevents slipping. It can also be used as a short extension for ¼" applications e.g. in combination with the Wera Zyklop Ratchets.

The basic idea for the prototype of the Kraftform handle - that the hand should dictate the design - has, right through to today, proved to be correct. In cooperation with the internationally recognised Fraunhofer IAO Institute, Wera developed a screwdriver handle designed to match the shape of the human hand as long ago as the 1960s. After a long development phase, the Wera Kraftform handle was launched to the market in 1968. It has been optimised through the years with new technologies, but has kept its proven shape. After all, the human hand has not changed either.
